func ExtractTxFromSignedPSBT

func ExtractTxFromSignedPSBT(psbtHex string) (string, error)

func GenerateBatchBuyingTx

func GenerateBatchBuyingTx(ins []*TxInput, outs []*TxOutput, sellerPSBTList []string, network *chaincfg.Params) (string, error)

func GenerateBatchBuyingTxPsbt

func GenerateBatchBuyingTxPsbt(ins []*TxInput, outs []*TxOutput, sellerPSBTList []string, network *chaincfg.Params) (string, string, error)

func GenerateSignedBuyingTx

func GenerateSignedBuyingTx(ins []*TxInput, outs []*TxOutput, sellerPsbt string, network *chaincfg.Params) (string, error)

func GenerateSignedListingPSBTBase64

func GenerateSignedListingPSBTBase64(in *TxInput, out *TxOutput, network *chaincfg.Params) (string, error)

func GenerateUnsignedPSBTHex

func GenerateUnsignedPSBTHex(ins []*TxInput, outs []*TxOutput, network *chaincfg.Params) (string, error)

func GetPsbtFromString

func GetPsbtFromString(psbtStr string) (*psbt.Packet, error)

func GetRandomHash

func GetRandomHash() (string, error)

func GetTransactionWeight

func GetTransactionWeight(tx *btcutil.Tx) int64

GetTransactionWeight computes the value of the weight metric for a given transaction. Currently the weight metric is simply the sum of the transactions's serialized size without any witness data scaled proportionally by the WitnessScaleFactor, and the transaction's serialized size including any witness data.

func GetTxHex

func GetTxHex(tx *wire.MsgTx) (string, error)

func GetTxVirtualSize

func GetTxVirtualSize(tx *btcutil.Tx) int64

GetTxVirtualSize computes the virtual size of a given transaction. A transaction's virtual size is based off its weight, creating a discount for any witness data it contains, proportional to the current blockchain.WitnessScaleFactor value.

func IsHexString

func IsHexString(s string) bool

func PayToPubKeyHashScript

func PayToPubKeyHashScript(pubKeyHash []byte) ([]byte, error)

func PayToWitnessPubKeyHashScript

func PayToWitnessPubKeyHashScript(pubKeyHash []byte) ([]byte, error)
